Bosses of an American jewellery company have taken aim at their former cover girl Kate Moss over allegations she has shot a near-identical campaign for a rival brand.The British beauty posed for luxury jeweller David Yurman last year (10) and she is now the face of French company Fred after designing a collection for the company. However, bosses at Yurman's firm allege the new photo campaign for Fred is "embarrassingly similar" to the picture Moss previously shot for them. A representative for David Yurman tells New York Post gossip column Page Six, "The Fred campaign is embarrassingly similar to the one David Yurman ran a year ago. When you are a leader in your category, you get used to people copying you. We are confident consumers know the difference."
